What does "father comes first and mother comes later" mean? Why is it that people on Kunlun Mountain can climb the mountain after Mi Jun said this sentence?

Once upon a time, there was a man who invited a fortune-teller to tell his parents a hundred years' life in order to arrange the affairs of his elderly parents. The fortune teller listened to his sad tone when he reported his parents' birthdays and said; Father died before mother! The fortune teller said; Sir, my mother is still here! The fortune teller said; Yes, my father is a hundred years earlier than my mother! The fortune teller said; There's my father! "The fortune teller said yes! Your father will be one hundred years ahead of your mother in the future! The soothsayer's wife passed by; Sir, you are wrong. His mother died young! "The fortune teller said yes! Even if dad is here, mom will die first! The charlatan lied. Guess your family situation and see if it's right. This sentence can make sense.

1。 Father died before mother. Father died before mother, and mother died later.

2。 Father died before mother, father was still alive, and mother died first.

That Lu Wu's question is simply not answered correctly. When he answered that women take a bath, he said it was wrong. When he answered a man, he said the answer should be a woman. So Mijun had to answer, but let him answer "Father died before mother".
